APPARATUS FOR SINGEING YARN.

Specicaton of Letters Patent.

Patented Dec. 23, 1919.

Application filed August 23, 1918. Serial No. 251,095.

To all whom t may concern:

Be it known that I, DAVID GRAVEL, a citizen of the United States, residing at Chattanooga, Hamilton county, and State ofTennessee, have invented and discovered certain new and useful improvements in Apparatus for Singeing Yarn, of which the following is a specification.

The present practice of preparing yarn for the majority of uses includes a sinoeing operation. This is at present accomplished by running the yarn from the spools on the creel through a warping machine and then balling the warp. The ball is then transferred to another frame and the yarn or warp passes through a tensioning device, then through an expansion comb mounted on a portable singeing machine. From this machine the yarn passes through a leese comb which is mounted on a stationary frame or support and is then rewound on a balling machine.

rlhis system not only necessitates balling the warp twice, but also requires the constant attention of the operator as there is no automatic means for stopping the machine should the yarn become broken or tangled. When the yarn does break it is necessary for the operator to lower the singeing device, which at the same time brings the yarn to a standstill but not until from sin to eight feet of the yarn has passed the singeing machine without being singed. After the broken yarn has been repaired, the singeing machine is moved forward on a pair of rails to a point in advance of the unsinged yarn and then raised into the singeing position again and slowly returned to its former position. rlhe system just described does not satisfactorily singe the yarn, as only the underside thereof is presented to the flame. y y

My said invention relates to an improved method and means for accomplishing this work by which the difficulties of `and objections to the system just described are obviated and the yarn is treated from both the lower and upper sides, all of which will be hereinafter described and claimed. i

` My system consists of running the yarn from the spools on the creel through a warping machine and over a series of flames or burners mounted in a stationary frame. From this frame the yarn passes` around an idle roller which turns the yarn into the reverse position Presenting its upper lsari'ace burners and the first idle roller, it is sub;

jected to the action of a second set of burners before it is finally wound by the balling machine.

Another feature of my invention resides in connecting the present automatic stop device of the warping machine with the burner shields and gas valves of my singeing machine. i

In the accompanying drawings which are made a part hereof, like reference characters designate similar parts in the several views, of which- Figure l is an elevation of a portion of the apparatus showing the creel, the warping and the balling machine,

The apparatus consists of a creel A upon which is mounted a series of spools 10 carrying threads of yarn 11 which are led through an expansion comb 12 mounted on any suitable warping `machine 'Bi The yarn passesunder and over a series of rollers `and 11.

through the drop wires of the stop; motion ofthe warping machine B in the form of a warp C which passes to the singeing machine D. i This machine comprises a frame 13 having supports 14e and 15 formed integral with an upper horizontal member 16 and an intermediate member 17' which have mounted thereon bearing brackets 18 supporting perforated `burner tubes 19. Valves 2O are secured to one end of the tubes 19 `and are connected to a manifold 21 by pipes 22. Gras is conveyed to the manifold through a pipe 23 provided with a valve 24C for cutting 0E the supply of gas to the entire machine. The lower end of pipev23 is provided ywith anfupstanding nozzle 25 which is mounted in the open end 26 of the manifold in such a position that air is drawn in and mixed with the gas before it enters the tubes 22. The stems of each of the valves are provided with a sprocket wheel 27 connected for simultaneous operation by sprocket chains 28, shown in Figs. 2 and 3. Connecting rods 29 have their upper ends joined to the chains 28 and their lower ends connected to a lever 30 fulcrumed at 31 to a bracket 32 secured to the support 14. This lever 30 extends twice as far on one side of its fulcrum 31 as it does on the other and the short end carries a link 33 which is connected to a lever 34 mounted on the stem of a quick-acting valve 35 in the gas pipe 23 which controls the flow of gas to the mani* fold 21. Each of the burners is provided with a pilot light 36 fed by the pipe 37 which is provided with a regulating valve 38 and which connects with the main gas pipe 23 at a point below the valve 24. The

, long end of the lever 30 has fulcrumed thereto'a connecting link 39 upon which is secured a counter-balance of proper weight. The lower end of the link 39 connects with the long arm 40 of a lever 41 fulcrumed at 42 to a beam 43 which is secured at one end to the standard 15 and at the other en d to a bracket depending from the frame of the working machine B.

y The short arm 44 is designed to alternately contactwith a pair of pivoted latches 45 and 46 when the machine is out of operation or in operation respectively. These latches 45 and 46 are pivoted on a T-shaped lever 47 fulerumed to the beam 43 at 48 and are held in normal positions by a spring 49 secured to studs 50 on each latch member. A foot member 51 is fulcrumed on a shaft 52mounted in the frame of the warping machine B and is connected to the lever 47 by means of the rod'53 to swing the lever from its upper to lower position7 orl vice versa. Thev lever 51 carries means to operate the device 54 for shifting the driving belt 55, which through a train of gears, opcrates to drive the balling machine E, shown only in'lFig. 1. The lever 51 is also e'onnected by means of a rod 64 with the stop vmotion of the warping machine.

Asa matter of convenience to the operator, a foot lever 56 is mounted on a shaft 57 which runs across the entire machine and has formed integral therewith an upstanding arm 58 connected to one arm 59 of a bell-crank lever 60 by means of a connecting rod V61. 1 The lever 60 is'pivoted on a stub shaft 62 carried by a depending bracket secured beneath the beam 43.. The other arm 63 of said lever y60 is connected also to the rod 53 so thatthe entire machinemay be started by. applying sufficient pressure to burners without being singed.

with asbestos 65 and which is mounted between two castings 66 to which' are secured two flat strips 67 and 68. The strip 67 serves to keep the shield in proper alinement and also serves to lift the warp away from the shield when in its upper position. The strip 68 is made longer than the shield and at one end is bolted to the sprocket 27 and the other end is bolted as at 69 to a cap 70 which closes the end of the tube 19. Counter weights 71 are secured to each of the sprockets 27 to overcome the weight of the shields 64. The usual expansion combs 72 and leese comb 73 are provided to keep the yarn separated. An idle drum 74 is also provided for carrying and returning the warp through the lower flame with a second idle drum 7 5 to again turn the warp to the eye 76 and over a third idle drum 77 turning the warp to the balling machine E.

The operation of the device is as follows:

The yarn passes from the creel, through the automatic stop motion of the warping machine and emerges therefrom as a warp. The warp then passes through the flames of the upper set of burners and around the idle drum, which turns the yarn, so as to present the unburned side to the lower set of burners, thereby completely singeing the nap from all sides of the yarn. The singed warp then passes around another idle drum and is then collected into the form of a band or rope by passing through an eye mounted on the same standard with another idle pulley from which it leads to the balling machine.

Should the yarn break in the warping machine, the automatic stop device would cause the lever 51 to raise, shifting the belt 55 so as to stop the balling machine and at the same time release the lever 44 from the latch 46 permitting the weight to rock the series of levers so as to shut off the valves 20 andv 35 and raise the several shields 64. During this interval the warp has advanced about six feet which causes a corresponding length of warp to pass the upper set of However when the yarn is repaired and the machine again started, by manually releasing the lever 44 from the latch 45 and depressing the said lever into locking engagement with the latch 467 the unsinged portion will be completely singed by passing through the lames of the lower set of burners.
